I like the fact that in subtracting two time series objects that there is some effort to align the series. So if I have a time series of that begins at 1 and one that begins at 2 a subtraction operation makes sure that the proper values are subtracted. But I am unclear as to the best way to build a time series with "holes". say that I ha...

Estimados usuarios-de-R: Tengo un problema. Si por ejemplo tengo una lista conformada por la serie historia del PBI de 10 paìses. >Tiempo <- seq(1:100) >plot(Tiempo, PP$"Serie 1", type="l",col="1") >lines(Tiempo, PPcapita$"Serie 2") >lines(Tiempo, PPcapita$"Serie 3") >lines(Tiempo, PPcapita$"Serie 4") >lines(Tiemp...

Can someone shed some light on this obscure portion of the help for lm? "Considerable care is needed when using 'lm' with time series. Unless 'na.action = NULL', the time series attributes are stripped from the variables before the regression is done. (This is necessary as omitting 'NA's would invalidate the time series attributes, and if 'NA's are omitted in the middle of the serie...

I could use some advice regarding xyplot. I've got 2 time series. Both cover approximately the same period of time (ie, 1940 to 2009). But one series has annual data and the other has monthly data. One refers to university enrollment; the other to unemployment rates. Both are currently in the same data frame. I'd like to use the monthly times series as a...

I wish to draw a graph representing multiple series (sets of x,y points). Each series has its own label and points within each series are joined by a line ordered by their X cooridnate. I would also like a legend automatically showing which each series is. Which high-level command can serve this purpose? I looked at my book but can't find...

Background: OS: Linux Mandrake 9.1 release: R 1.9.0 editor: Xemacs 21.4 frontend: ESS 5.1.23 --------------------------------- Colleagues I have two time series (upwelling index and water temperature) of evenly spaced, daily data over 18 months, but the upwelling index series has a gap of about 2 months right in the middle of it. I want to do the acf, pacf, ccf, and a cross-spectral analysis of the two series. I realise that I could just break each ser...

Hi R users, I am doing cross correlation analysis on 2 time series (call them y-series and x-series) where I need the use the model developed on the x-series to prewhiten the yseries.. Can someone point me to a function/filter in R that would allow me to do that? Thanks in advance for any help! -- View this message in context: http://www.nabble.com/Whitening...

I have been working with the base time series object (ts) and I had a couple of questions that hopefully this group can help me with: 1) What is the best why to append an observation to an existing time-series? Suppose I have a time series: t <- ts(1:12, frequency=5) This would generate two complete cycles and one remainder. Now I woul...

Bueno, realmente no es necesaria que la serie esté centrada en este caso, ya que estoy sumando un ruído blanco Un saludo From: fjroar en hotmail.com To: caaperezan en gmail.com; r-help-es en r-project.org Date: Wed, 5 Nov 2014 13:00:49 +0000 Subject: Re: [R-es] Agregar ruido a una serie de tiempo Hola buenos d?as: Yo cuando he tenido que ha...

I am interested in a statistical comparison of multiple (5) time series' generated from modeling software (Hydrologic Simulation Program Fortran). The model output simulates daily bacteria concentration in a stream. The multiple time series' are a result of varying our representation of the stream within the model. Our main question is: Do the different...

Hi Users, I have daily series of data from 1962 - 2000, with the data for February 29th in leap years excluded, leaving 365 daily values for each year. I wish to convert the daily series to monthly series. How can I do this using the zoo package or any other package? Thanks ZABLONE OWITI GRADUATE STUDENT Nanjing Univ...

Es posible agregar ruido a una serie de tiempo Tengo series de tiempo que tienen un comportamiento funcional, quisiera agregar ruido para que parezcan señales mas reales. Normalmente las series de tiempo se suavizan a traves de filtros, es posible hacer el proceso inverso con algun paquete de R Gracias por la atención CARLOS ANDRE...

Hi, I have a matrix and time series "xmat". I have no problem executing any matrix functions except t(xmat) which gives the following error message. My question if "xmat" is a matrix why I can not execute this matrix function?? converting the time series and matrix into a data frame solves the problem >dim(xm...
